Passos da solução

Represent the numbers with

x

:

First number : x

Consecutive number 1 : x + 2

Consecutive number 2 : x + 4

Consecutive number 3 : x + 6

Consecutive number 4 : x + 8

A.T.Q.:

x + x + 2 + x + 4 + x + 6 + x + 8 = 100

Resolver

x + x + 2 + x + 4 + x + 6 + x + 8 = 100 : x = 16

x + 2 = 16 + 2 = 18

x + 4 = 16 + 4 = 20

x + 6 = 16 + 6 = 22

x + 8 = 16 + 8 = 24

Select the smallest solution:

16

The smallest number : 16
